3. What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?
